Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

# Tulip family network device configuration

config NET_TULIP
	bool "DEC - Tulip devices"
	depends on (PCI || EISA || CARDBUS)
	help
	  This selects the "Tulip" family of EISA/PCI network cards.

if NET_TULIP

config DE2104X
	tristate "Early DECchip Tulip (dc2104x) PCI support"
	depends on PCI
	select CRC32
	help
	  This driver is developed for the SMC EtherPower series Ethernet
	  cards and also works with cards based on the DECchip
	  21040 (Tulip series) chips.  Some LinkSys PCI cards are
	  of this type.  (If your card is NOT SMC EtherPower 10/100 PCI
	  (smc9332dst), you can also try the driver for "Generic DECchip"
	  cards, below.  However, most people with a network card of this type
	  will say Y here.)

	  To compile this driver as a module, choose M here. The module will
	  be called de2104x.

config DE2104X_DSL
	int "Descriptor Skip Length in 32 bit longwords"
	depends on DE2104X
	range 0 31
	default 0
	help
	  Setting this value allows to align ring buffer descriptors into their
	  own cache lines. Value of 4 corresponds to the typical 32 byte line
	  (the descriptor is 16 bytes). This is necessary on systems that lack
	  cache coherence, an example is PowerMac 5500. Otherwise 0 is safe.
	  Default is 0, and range is 0 to 31.

config TULIP
	tristate "DECchip Tulip (dc2114x) PCI support"
	depends on PCI
	select CRC32
	help
	  This driver is developed for the SMC EtherPower series Ethernet
	  cards and also works with cards based on the DECchip 
	  21140 (Tulip series) chips.  Some LinkSys PCI cards are
	  of this type.  (If your card is NOT SMC EtherPower 10/100 PCI
	  (smc9332dst), you can also try the driver for "Generic DECchip"
	  cards, above.  However, most people with a network card of this type
	  will say Y here.)

	  To compile this driver as a module, choose M here. The module will
	  be called tulip.

config TULIP_MWI
	bool "New bus configuration"
	depends on TULIP
	help
	  This configures your Tulip card specifically for the card and
	  system cache line size type you are using.

	  This is experimental code, not yet tested on many boards.

	  If unsure, say N.

config TULIP_MMIO
	bool "Use PCI shared mem for NIC registers"
